MANUFACTURE OF GLASS ARTICLES.

SPECIFICATION forming pm of Letters Patent No. 275,564, dated April 1o, Issa.

Y Application filed February 13, 1883. (No model.)

To all whom it may concern Be it known that I, THOMAS B. ATTEBBURY, a citizen of theUnted States,residin g at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Manufacture ot' Glass Articles; and AI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable` others'skilled in the art to which it appertains to make and Vuse the same.

My invention relates to the manufact-nre of glass vessels provided with a guard, cap or iange which partially incloses the upper portion of the cavity, to prevent the contents of the vessel from coming in contact with the mustache, to hold back the froth or foam of aerated or malt liquors, and also to prevent the ice whichmay be in the vessel from being poured out`or from coming in contact with the lips of the person drinking from suchvessel.

`To this end my invention consists in pressing the main body of the article in one piece or section, providin git with offsets or marees7 to receive the guard or flanged portion, which is pressed in a separate mold and joined to the main body while at a welding-heat.

In a separate application filed by me J an uary 20, 1883, Serial No. 82,446, I formed the main body of the article, together with the guard or dan ge, atone andthe same operation of pressing, and subsequently reheated and folded the ange or guard down over the top of the article While at a welding-heat and joining it thereto, so as to form a guard or flange.

In this invention I employ essentially the same process shown and described in Letters Patent No. 181,618, granted to me August 29,

V1876, but with such changes and modifications the mold for forming the guard or ange. Fig. 3 is a side elevation of the bottom of the liange or guard forming mold. Fig. 4 is a top or plan view of the article with the guard or flange thereon.

A A indicate the sections of an ordinary two-part mold in which the article is pressed, and I may have the mold-cavity of any desired conguration.

B is the mold or plunger ring, of the usual or of any desired form, on the under side of which is formed one or moresegmental flanges, a, which forms in the inner upper edge of the cavity of the article recesses or marees b, to receive the guard or flange, made with special reference to till such marees and afford a perfect seat for said guard or flange.

C is the plunger, of the ordinary or any desired construction, operated by any of the wellknown power or hand presses.

I) lis the mold for forming the guard or ange, and may be of any suitable or convenient construction. In the present instance, however, I have shown the mold-cavity of semi-cylindrical form in cross-section, with a plunger, E, having on its lower end projections and cavities which will give the proper form to theguard or flange, as shown at c, Fig. 4. In practice, however, l may make the mold-cavity ofthe shape which is desired to j be given to the flange or guard, and then make the plunger to conform to said cavity.

In Fig. 4 I have shown a top or plan view of a beer-mug or handled glass made in accordance with my invention. F indicates the body of the article, and c the flange or guard joined thereto, while the dotted lines show the depth of the offsets or marees,into which is fitted the ends of the guard or ange. The main body of the article and the guard or liange are made in the usual manner, and at or about the same time. The guard or lian ged portion is then removed from its mold while still at a welding-heat, and adjusted in position in the offsets or marees formed in the main body of the article, when the two sections will unite, forming a tight joint. It' necessary, a tool is. passed rapidly over the joints with light pressure to insure a more' perfect union of the parts.

I do not wish to limit myself to the manu facture of beer-mugs, goblets, glasses, or other drinking-vessels, as it is obvious that waterpitchers, molasses-pitchers, cream-j u gs, gravy- ICO dishes, and an endless variety of articles can be produced with a guard or flange in accordance with my invention.

The main body of the article may be pressed without the oifsets or marees, and the upper edge made perfectly plain, to which the guard or shield flange is attached at a welding-heat, and finished by tools and lire-polishing. In either instance, or by whichever method made, the guard or shield ange c is out away or formed with a recess at its outer edge to form a pouring` or drinking orifice, c', as shown in Fig. L

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

l. As an improvement in the manufacture of glass vessels having guard or shield anges, forming the article in sections in separate molds, and then joining the sections while ata welding-heatto cause them to unite, as setforth.

2. As an improvement in the manufacture of glass vessels or articles having guard or shield flanges, forming the article in sections inseparate molds, the main body of the article being formed with offsets or marees to receive the guard or shield flange, the sections being united while at a welding-heat, as set forth.

3. As a new article of manufacture, a glass vessel having a shield or guard dange made separately from and joined to the main body of the article while at a welding-heat, as set forth.

4. A glass vessel or other article the main body of which is formed with offsets or mareos to receive a guard or shield ange, said flange being provided with a drinking or pouring ori tice, and the two Sections being united at a weldingheat, as set forth.

In testimony whereof I hereby affix my signature in presence of two witnesses.
